Knife sharpening questions

[Chuck]

Hello, I am new to this forum. This is not exactly a rigging question, but I was wondering if anyone could give me some advice on knife sharpening tools and techniques, or point me towards some books or websites that would be helpful. I've done some of my own research on this topic, and turned up a bewildering array of information, and I was hoping to get some expert opinions to sort it all out.

1) What kinds of sharpening stones or devices should I use? Oil stones? Water stones?

2) Where can I find a good, clear set of instructions for sharpening a knife?

Thanks in advance for your advice.
